  In recent years, portable electronic devices having a waterproof function are increasing. The waterproof function of the portable electronic device is realized by a waterproof packing incorporated in the housing preventing water from entering the housing.

  Patent Document 1 describes a portable electronic device including a frame-shaped waterproof packing that surrounds a display opening.

  In addition, there is a foldable portable electronic device in which one housing and the other housing are connected at an end. In such a foldable portable electronic device, when a folding operation is performed by a user, the casings may come into contact with each other and be damaged.

  Patent Document 2 describes a foldable portable electronic device in which a shock absorbing cushion is installed in a contact portion of one housing with the other housing.

JP-A-2005-333290 (paragraphs 0024 to 0032, FIG. 1) Japanese Patent Laying-Open No. 2005-1559566 (paragraphs 0032 to 0050, FIG. 6)

  However, a waterproof packing was installed on the electronic device for the purpose of preventing water from entering the housing, and an impact absorbing cushion was installed on the electronic device for the purpose of absorbing the impact during folding operation. In this case, there are problems that the number of parts and assembly man-hours of the electronic device increase, and the manufacturing cost increases.

  Therefore, the present invention prevents an increase in manufacturing cost, prevents the penetration of water into the casing and damages the casing during the folding operation, and the waterproof of the folding portable electronic apparatus and the waterproofing of the folding portable electronic apparatus. The purpose is to provide a structure.

A foldable portable electronic device cushion according to the present invention includes one housing and the other housing, in which one surface of one housing is covered with the other housing and one surface is opened. A folding portable electronic device cushion that can be set in an open state, and is provided on one housing, protrudes from one surface and contacts the other housing in a closed state, and a side surface A body portion that is sandwiched and adhered between an outer side surface of a frame component member that constitutes a frame of one surface and an inner side surface of a rear surface component member that covers a rear surface that is a surface opposite to the one surface in one housing; only contains, on the outer surface of the frame components of the one casing, the fitting portion of the convex shape which abuts the upper surface to the bottom surface of the claw portion of the convex shape provided on the inner surface of the back component is formed The fitting part of the frame component member penetrates the cushion, and the upper surface is the back A through hole in contact with the bottom surface of the forming member, characterized in that provided.

A waterproof structure of a foldable portable electronic device according to the present invention includes one housing and the other housing, in which one surface of one housing is covered by the other housing and one surface is open. A folding portable electronic device waterproof structure that can be set in an open state, and is provided on one casing, and protrudes from one surface and contacts the other casing in the closed state A cylinder that is sandwiched and adhered between an outer side surface of a frame component member that constitutes a frame having one side surface and an inner side surface of a rear surface component member that covers a rear surface that is the surface opposite to the one surface in one housing. And a convex shape in which an upper surface is formed on the outer surface of the frame component member of one housing and is in contact with the bottom surface of the convex nail portion provided on the inner surface of the rear component member. A fitting part is provided, and the fitting part of the frame component member penetrates the cushion. Top surface, characterized in that the through hole in contact with the bottom surface of the rear component is provided.
